Mr method and apparatus for determining coronal and sagittal image planes from an image data set of a knee joint

A magnetic resonance imaging apparatus comprising:

• a magnetic resonance scanner adapted to receive an examination subject therein to acquire magnetic resonance data from the subject;
• a computer connected to said magnetic resonance scanner for operating said magnetic resonance scanner to acquire said magnetic resonance data;
• said computer being provided with an image data set representing a transverse tomographic image of a knee joint of the subject, and said computer electronically analyzing said data set using an analysis algorithm to identify the medial condyle and the lateral condyle of the femoral bone head of said knee joint, and to identify a point on the medial condyle and a point on the lateral condyle that, in combination, define the coronal plane, and said computer electronically identifying the sagittal plane proceeding perpendicular to the identified coronal plane;
• and
• said computer controlling acquisition or representation of at least one of a coronal slice image and a sagittal slice image oriented dependent on at least one of the identified coronal plane and the identified sagittal plane.
